1 Claim.

This invention relates to a bolt board and more especially to a quickly attachable end piece to be placed over the end of the bolt board. Bolt boards were formerly made of wood but now are usually made by folding a sheet of corrugated paper to provide a bolt board on to which bolts of cloth are wound. This usually presents an uneven and unfinished end portion at each end of the bolt board and makes an unsightly appearance and also is liable to injure the edges of the cloth wound thereon.

It is also difficult to place printed matter on the ends of these boards and therefore it is an object of this invention to provide a foldable blank adapted to he slipped over each end of the bolt board and having a tongue whereby a gripping effect is obtained which prevents the end pieces from sliding off of the ends of the bolt board. Then the cloth is usually wound so that its edges overlap the caps which are placed over the ends of the bolt board to insure that they are held in position on the bolt board. Also this foldable blank, while in fiat position lends itself easily to printing the trade-mark, name of manufacturer, type of goods, and the like on the end portions of the blanks which are then folded and inserted over the ends of the bolt board.

The board lends itself to speedy production in that the corrugated part is run on a regular corrugating machine, creased and then if desired taped on automatic tapers and both operations could be performed at one time, and in the same machine.

The end pieces lend themselves to mass production in that they can be printed a large number at a time upon a large sheet and then this sheet can be die cut to produce a plurality of the end pieces ready for folding to slip over the ends of the bolt board. Or, if desired, after the end pieces have been die cut and separated, they can be glued on automatic equipment. The bolt boards can be folded and as they come from the machine sidewise, an operator on each side can slip the caps or end pieces over the ends of the blank as it comes from the machine. Another advantage of these end pieces is the fact that ordinarily a label or wrap is glued at the ends which always presents an untidy appearance and whereby by the present invention, the appearance is uniform and clean looking.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure 1 is an isometric view of a bolt board a 2 and showing the end caps in assembled position and inserted over the ends of the bolt board;

Figure 2 is an isometric View of one of the end caps folded and glued together and ready for insertion over one end of the bolt board;

Figure 3 is a view similar to Figure 2 but showing the main flap in partly opened position and before it is completely folded ready for insertion over the bolt board as shown in Figure 2;

Figure 4 is a plan view of the blank before it is folded;

- Figure 5 is an enlarged cross sectional view through the bolt board taken along the line 55 inFigure l;

Figure 6 is a sectional view through one of the endpieces after it has been assembled, taken along the line 6-6 in Figure 2;

Figure '7 is an isometric view of a slightly modified form of bolt board but having the same end pieces fitted thereover;

Figure 8 Ba cross sectional view taken along the line 8-8 in Figure 7;

. Figure '9' is a cross sectional view taken along the line 9,'9 in Figure 7;.

Figure 10 is an edge of one of the bolt boards with cloth wound thereon and with the central portion thereof broken away.

'Referring more specifically to the drawings, the numeral It indicates broadly a blank from which the end pieces or caps for slipping over a cloth bolt board. are formed. This blank comprises a main body portion I I having crease lines I5 and I6 along which the blank is folded to form a first side wall I'I.

Between the crease line It and the lefthand end of the blank in Figure 4 is a tab I8 which is adapted to occupy a horizontal position and in spaced relation to the portion II. This tab can have adhesive applied to the lower side thereof in Figure 4 or an adhesive 28 can be applied to the top side of a top portion'ZI because the adhesive portion 20 and the end of the ortion I8 are in overlapping position and adhesively secured together.

the assembled member as is clearly shown in Figure 3.

There is a crease line 35 provided along which the material is bent to form an end wall 36. I-Iingedly connected to the end wall by a crease line 31 is top tab 38. This top tab 38 has cut away portions 39 and 40 nearthe ends thereof and has a transverse crease line 41 forming a turn-under tab 52 which is adapted to be turned in and abut against the cloth board to be pres; ently described.

In assembling the blank to form the finished unit as shown in Figures 1 and 2, th naterial is bent along the crease line l5, l9, 2 4 and 21s. and the ends of tab I 8 and top Z.|v are oyerelapped and adhesively secured together. Then the tabs 29 and 30 are folded inwardly. and thenthe ma: terial is bent upwardly along the crease line 35 to form an end wall 36 fitting against the end: of a the cloth board, and then the material is creased alon the crease line 31 to form the top tab 38 which extends upwardly andover the top. of the assembled unit. The restricted portion occurring between cut away portions 39 and 48 is fitted into the gap 12 and the edges thereof are slipped into the diagonal slots {3 and l d and the tab 42 is turned underneath the front edge of; the gap l2 and exerts a gripping efieot on the. end oi the cloth board to prevent itsaocidental removal once it is installed in position.

A cloth board is usually made from corrugated paper and can be in either of; the form shown in Figures 1 and or of the form shown in Fig ures '7, 8 and 9. When it is formed from; the type of light stock board shown. in Figures 1 and 5 it is indicated broadly by reference character- 50 and has a bottom portion 51 whichiS bent at points 52 and 53 and is directed upwardly. and bent at points 54 and 55 and then is again bent at points 55, 51, 5B and 59, then when firmly pressed in this position, will remain in this position. Without any adhesive or the like, because the units slipped over each end thereoi will hold itv in assembled position. This forms. a three layer board comprising the main layer 5 I and half width layers 45, 46, 41 and 4 8.

This type of board can be made of heavier stock as shown in Figures 7 8 andQ. In Figures 7, 8 311d 9 h uqi i q mn ama ej as-e portion 60. bent at each end as at El, 62,53 and 64 providing upper halt portions 65; andififi which can, if desired, be adhesively secured in position by means of a strip of gummedpaper 61.

In either event when the cloth boards are assembled the end or cap members formed from the blanks H] are slipped over the ends of the board and then the assembly is ready for the winding ofcloth thereon.

This cloth is usually woundthereon andisindicated at and partially covers the end pieces or caps which are slipped over the. ends of the cloth board before the cloth is wound thereon and thus the cloth holdsthe end pieces or caps, n p on o he e ds of he cloth.- boardiand: prevents their accidental loss therefrom n t e rawings. an s eqifis ai aa the e. h
